What the DL100 is and what comes in the box
The Tapo DL100 is a TP-Link Wi-Fi deadbolt with a backlit keypad, Bluetooth as a fallback when Wi-Fi is unavailable, and two backup keys. The listing's model and part number is Tapo DL100, and Tapo's datasheet and product page are both titled for the DL100.
The datasheet's package list is the lock, an installation mounting plate, latch bolt, strike plate, dust box, four AA/LR6 batteries, a silicone cover, keys, screws, a measuring template, installation guide stickers and a quick start guide. The listing also names a USB adapter cable. The datasheet gives the outside assembly as 5.88 by 2.65 by 2.20 inches and the inside assembly as 6.57 by 2.85 by 2.02 inches.
Door fit
The listing says the DL100 installs on the standard lock hole sizes of 2-1/8 inches (54 mm) and 1-1/2 inches (38 mm), with no drilling or extra holes. Tapo's product page says it installs on a standard deadbolt with no extra holes, and links to a door and lock size compatibility check that we did not use.
Neither the datasheet nor the product page we read gives a supported door thickness or backset range, so check the compatibility tool or the installation guide against your door before buying. We do not reproduce installation steps.
Batteries: listing and maker figures differ
The lock runs on four AA batteries, which are included, with a USB-C port on the outside for emergency power. Tapo's page and datasheet give battery life of up to 7 months in Wi-Fi mode and up to 10 months in Bluetooth mode, based on TP-Link lab tests assuming 20 unlocks a day. The listing states up to 200 days in Wi-Fi mode and 300 days in Bluetooth mode.
Tapo's product page adds a caveat worth reading if your door faces winter weather: alkaline batteries may suffer reduced life and unlocking failures in cold environments because of poor low-temperature performance. The datasheet lists an operating range for the outside assembly of -22°F to 158°F. For emergency USB-C power, Tapo says your phone must support power output.
Codes, access and alerts
The datasheet lists up to 200 PIN codes, one-time codes, scramble codes that let you type random digits around your real code, emergency unlock, mechanical key and automatic locking. Tapo's page describes permanent, one-time and scheduled codes, and the datasheet gives 15 seconds as an example auto-lock delay. Both describe a lockout after a set number of wrong codes with an alert to your phone.
The Tapo app shows a timestamped activity log and whether the door is closed, and sends real-time alerts. Voice unlocking through Alexa or Google Assistant requires a voice PIN, and Tapo notes that requirements vary by platform. Tapo's page also states that this lock requires an internet connection.
Wi-Fi, security and weather rating
The datasheet lists Wi-Fi 802.11 b/g/n on 2.4 GHz only, plus Bluetooth Low Energy 5.0, with 128-bit AES encryption over SSL/TLS and WPA, WPA2 or WPA3 network security. Smart integrations are Google Assistant, Amazon Alexa, SmartThings and IFTTT. Tapo says it has signed CISA's Secure-by-Design pledge.
The datasheet rates the outside assembly IP54 and states the inside assembly is not weatherproof. It lists ANSI/BHMA Grade 3 certification, and the listing and Tapo's page describe the lock as BHMA certified. We do not interpret what those ratings mean beyond what Tapo states.
Warranty and what we could not confirm
Neither the datasheet nor the product page nor the listing we read states a warranty length for the DL100. Ask TP-Link or the seller for the warranty terms before relying on them.
We also did not read the quick start guide or full user guide, so any installation limits, battery replacement steps or reset procedures should be taken from those documents rather than from this page.
